Abstract

La présente invention concerne une courroie striée (10) comprenant une couche inférieure en caoutchouc (12), une couche adhésive en caoutchouc (16) et de la toile (22). La couche inférieure en caoutchouc (12) contient de la fibre courte (14), certaines de ces fibres dépassant de la surface (12S) de la couche inférieure en caoutchouc. Dans la couche inférieure en caoutchouc (12), on utilise comme agent renforçant du FEF qui est un noir de carbone dont la superficie moyenne en azote n'excède pas 49 m2/g selon ASTM D1765-01, ce qui permet de produire une fine irrégularité superficielle (12S) de la couche inférieure en caoutchouc. Cela permet d'éviter la production de bruit pendant l'utilisation de la courroie striée (10). En outre, grâce à l'utilisation de l'agent de renforcement, on arrive à conserver une rugosité superficielle appropriée, même après disparition par usure de la fibre courte (14) dépassant de la surface (12S) de la couche inférieure en caoutchouc, et donc à bloquer la production de bruit.
